Mathematical modelling of palaeocommunity trophic dynamics is a useful tool for investigating food resource availability and intraguild competition. We use a mathematical model based on Leslie Matrices to obtain estimations of the available resources for secondary consumers. Although humans inhabited the Sierra de Atapuerca since more than one million years ago to the Neolithic, the evidence of human presence is not continuous over time. TD8 level of Gran Dolina site, about 600,000 years old, lacks any evidence of human presence. We analyze trophic resource availability for secondary consumers at TD8 to test the hypothesis that human absence coincides with low resource availability. Our results suggest an environment rich in trophic resources, able to sustain a rich guild of secondary consumers.
